I never knew how much that RecordRadiusScale setting in the .ini influenced the shadows. It’s the only thing that has changed between the two screenshots
Especially check out the shadows of the box on the floor towards the camera.
this is 4.11 with portals / medium built / static lighting level scale 1.0 / indirect lighting bounces 70 / indirect lighting quality 1.0 / indirect lighting smoothness 1.0
and a skylight with a hdr map
